Use of ultra-low dose computed tomography versus abdominal plain film for assessment of stone-free rates after shock-wave lithotripsy: implications on emergency room visits, surgical procedures, and cost-effectiveness.

The aims of this investigation were: (1) to compare residual stone-fragment (RSF) detection rates of ultra-low dose computed tomography (ULD-CT) and abdominal plain film (KUB) in urolithiasis patients undergoing shock-wave lithotripsy (SWL), and (2) to evaluate the downstream sequelae of utilizing these two disparate imaging pathways of differing diagnostic fidelity. A retrospective chart-review of patients undergoing SWL at two high-volume surgical centers was undertaken (2013-2016). RSF diagnostic rates of ULD-CT and KUB were assessed, and the impact of imaging modality used on subsequent emergency room (ER) visits, unplanned procedures, and cost-effectiveness was investigated.

Endocrine, Sexual Function, and Infertility Side Effects of Immune Checkpoint Inhibitor Therapy for Genitourinary Cancers.

Purpose Of Review: Immune checkpoint therapy has grown in prominence in the last few decades and is being increasingly utilized in treatment of advanced cancers. Although information on toxicities of these drugs is forthcoming, not much is known regarding the toxicity profile of these drugs from a sexual function standpoint. We undertook the current review to appraise the literature for endocrine/sexual side effects of anti-PD-1/PD-L1 and anti-CTLA-4 therapy.
